Title: Improvements in or relating to floor treating or polishing machines
IPC: A47L11/40
Filed: 1938-05-30
Abstract: 515,373. Floor-treating machines. STAEHLE, G. May 30, 1938, No. 16121. Convention date, May 31, 1937. [Class 138 (i)] [Also in Group XXVIII] A floor-polishing machine of the kind comprising floor-treating elements, shown as brushes 1, mounted to rotate about vertical axes in a casing 6 from which dust is sucked by a fan, is provided with a sealing ring 7 of felt or rubber which adjusts itself automatically on the casing to compensate for wear of the brushes. As shown in Fig. 3, the ring 7, formed of two plies of felt, is pressed into contact with the floor by springs 24, and is cut away at its lower edge to form recesses 20, for the entry of air into the casing. In modifications, a similar ring is pressed towards the floor by wire springs. In another modification, Fig. 9, the ring is carried by corrugated metal clips 33 which engage its inner ply 7" sufficiently tightly to prevent undesired displacement; but to allow the ring to rise relatively to the casing as the brushes wear. The Specification as open to inspection under Sect. 91 describes also constructions in which the ring is held adjustably by clamping screws. This subject-matter does not appear in the Specification as accepted.

Title: Apparatus for sorting small articles
IPC: B07C5/342
Filed: 1948-06-16
Abstract: 642,284. Sorting photo - electrically. FRANKEL, H., and GUNSON (SEEDS), Ltd., R. W. June 16, 1948, No. 16180. [Class 40 (iii)] In a method of sorting small articles described in Specification 617,276, beans, for example, fall one at a time over the metallic tip of an insulated shoot, this end constituting an electrode. As each bean reaches the tip it is examined by a photo-cell and receives a charge from the tip according to its colour so that on subsequently falling between two plates at a high potential difference the charged bean is deflected to a receiving pan. According to the invention the articles are now charged by a corona discharge initiated between a needle 18 and an electrode 19, each individual bean being viewed by a photo-cell 13 as it falls from a shoot 10. In a modification of the invention the corona discharge instead of being initiated by each bean of a predetermined colour may be continuous and may be deflected magnetically away from the path of an article which is not to be charged or vice versa. The light source 12 may be mounted in an internally reflecting spherical housing 20 (Fig. 2), the beans entering through a small hole 21 and leaving through another 22 and the photo-cells being mounted in the side of the sphere as at 23. The article may be fed to the light source by feeding apparatus of the type described in Specification 642,283. They may also be conveyed between adjoining horizontal edges of a pair of inclined belts or between the peripheries of two contact rollers.

Abstract: 1,098,333. Keysenders. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. April 5, 1966 [April 15, 1965], No. 16201/65. Heading H4K. In a V.F. keysender, the switch actuating members are arranged parallel to each other and are each pivoted about an axis transverse to the rows of push-buttons. The V.F. signals transmitted may conform to the National 2 out of 5 code. The members consist of hinged plates 4 some of which are directly operated by projections 2B depending from the buttons 2 while others are operated indirectly through the intermediary of one or more cross-bars 6 associated with each row and pivoted about axes parallel to and adjacent to the row. By removing the projections 2B or by cutting slots in the cross-bars so that they cannot be actuated by the leading edges 2C of the pushbuttons when these are depressed, various special frequency combinations can be obtained (Figs. 3A, 3B, 3C not shown). The switches actuated by members 4 may be printed circuittype wafer switches 8, plunger switches (Fig. 1B, not shown), cam-operated spring contacts (Fig. 1A, not shown), or multi-contact spring sets (Fig. 1C, not shown). The return biasing means for the members 4 may be of any conventional form. Preferably the buttons have individual restoring means which may comprise helical springs (Fig. 4A, not shown), multipoled ceramic ring magnets (Figs. 4B and 5, not shown), or a snap-action spring (30, Fig. 4C, not shown). The two latter means provide an initial restraint for the button when it is depressed so that accidental operation is minimized. The under surface of the iron stopplate, against which the ring magnet is normally retained, is provided with a thin membrane which acts as a sound-damping medium.

Title: Improvements in or relating to thermodynamic power plant
IPC: F02C6/18
Filed: 1949-06-17
Abstract: 675,971. Hot gas engines and power plant. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. June 17, 1949 [June 21, 1948], No. 16204/49. Class 7(i) [Also in Group XXVI] In a power plant comprising at least one turbine, one compressor and one hot gas reciprocating engine the hot gases generated in the combustion chambers of the turbine are used to heat indirectly the working medium of the reciprocating engine before passing to the turbine. In Fig. 1a, a turbine 1 drives a compressor 2. The compressed air is heated at 5a by the turbine exhaust and is burnt with fuel in a combustion chamber 5. The products of combustion drive the turbine 1 and air for a reciprocating engine 7, which provides useful power, is heated indirectly in the chamber 5. The combustion products may ,give up their heat in an exchanger to air which is there used in the turbine 1. Alternatively, the turbine 1 provides useful power and the engine 7 drives a reciprocating or other compressor. The turbine may also drive a pre-compressor. The engine 7 may be replaced by several smaller engines each driving a compressor. The compressors may be arranged in parallel or series-parallel. The turbine may be in two stages with re-heating. The combustion products from chamber 5 may be augmented by a second combustion chamber in parallel with the chamber 5. Or, the second combustion chamber may provide gas for a second useful power turbine. In Fig. 6, the combustion products from chamber 14 are used in two turbines, 50, 16 which provide useful power at 56 and A. The turbine 50 also drives a compressor 51 which deliveres to a compressor 11 driven by the engine 10. The turbines 50 and 16 may be interchanged and the lowpressure one may use gas tapped from an intermediate point of the other. The turbines 50, 16 may be in parallel. In Fig. 8, air from a compressor 71 is burnt with fuel in two combustion chambers 63, 65 in series and the combustion products are used in a turbine 72 which drives the compressor 71. The chamber 63 provides hot gas for the engine 10 which drives a compressor 11. The chamber 65 heats air or other gas in a closed circuit which includes a useful power turbine 16. The combustion chamber 65 may be replaced by a heat-exchanger in which heat is transferred to the closed circuit air of turbine 16 from the combustion products leaving the chamber 63. In that case, the turbine 72 is omitted and the compressor 71 is driven by the reciprocating engine 10.
